In general, in the case of the structure constituting the device to form a predetermined hole by using a drill in the structure for the assembly of the structure between the structures, in particular in the aircraft manufacturing field assembly and stringer between the wing structure (vent box) of the aircraft and In order to assemble wing skins and the like, a plurality of holes are often formed at uniform intervals in the structure.

Conventionally, in order to form a hole in such a structure, a worker directly grips an air drill by hand while fixing the structure to a jig having a predetermined shape, and forms a hole, and in particular, maintains a right angle at a predetermined interval in the structure. In forming a plurality of holes, a preliminary hole was formed to be formed, and the final hole was formed to be formed secondly.

However, these conventional hole forming operations are not only subjected to complicated pre-working processes such as adjusting the spacing between each hole, right angles, and preliminary hole processing, but also highly dependent on the skill of the operator. It takes a lot of work time to form a decrease in the efficiency of the work, there is a problem that the quality of each hole forming is not constant.

In addition, in the process of forming a hole using an air drill, when the worker is working for a long time, there is a problem that the fatigue of the worker increases due to an unstable posture, thereby including a risk of an industrial accident.

The present invention has been made to solve the above-mentioned problems of the prior art, in the formation of a hole in a structure, complicated pre-working such as adjusting the spacing and right angle between the holes, preliminary hole processing, etc. is unnecessary and according to the automation of the work process The object of the present invention is to provide a drill jig for hole machining, which can improve the efficiency of hole forming work and minimize the risk of industrial accidents.

In addition, the elastic means 460 is an elastic body (eg, a compression coil spring) that is extrapolated and mounted on the shaft 430 between the first handle bush 450a and the second holder bush 441b.

Referring to the operation of the drill jig for hole processing according to the present invention configured as described above are as follows.

       Figure 4 is an exemplary view showing a working example for processing a hole in the structure using a hole drilling drill jig according to the present invention, the worker to form a desired hole in the structure using the hole drilling drill jig according to the present invention In order to close the structure (1) to the rear surface of the frame 100 structure consisting of the vertical frame (101, 102) and the horizontal frame (104, 105), The horizontal movement clamp 200 is moved horizontally on the horizontal frames 104 and 105 so as to be positioned at each corner portion of the structure 1 to stably clamp and fix the structure 1, in which case each moving body For example, in a clock room, the adhesion control unit 233 provided at one end of the bending bar 232 in a state where each corner portion of the structure 1 is located between the other side of the space and the space of the contact plate. When rotated by the bending bar 232 is moved backward by the screw movement of the mutual fastening portion as the close contact plate 231 coupled to the other end of the bending bar 232 is opposite to the other side of the moving body 210 Thereby clamping the structure 1.

       As described above, when the structure 1 is clamped by the horizontal moving clamp 200, the hole 1 ′ is formed in a predetermined portion of the structure 1, in which case the worker has a hole 1 ′ formed point and The drill 3 is positioned at the desired hole 1 'machining forming point by horizontally moving the horizontal moving bar 300 so as to be positioned on the same vertical line, and vertically moving the drill mounting unit 400 installed on the horizontal moving bar 300. After the operation, the handle portion 450 is manipulated to form a hole 1 ′ at a desired point of the structure 1. That is, when the worker intends to form the hole 1 ′ on the predetermined portion of the structure 1, the worker pushes the handle handle 451d of the handle portion 450 in the direction of the front structure. Accordingly, the drill 3 is mounted. The drill holder portion 440 of the drill mounting portion 400 is brought closer to the structure 1 side on the shaft 430, the hole 1 'is formed in the structure 1 by the drill (3). Herein, the forward operation of the drill holder 440 by the manipulation of the handle part 450 will be described in more detail. When the operator pushes the third link 451c provided with the handle handle 451d forward, the third link ( The second handle bush 450b hinged to the middle portion of the 451c is moved forward on the shaft 430 and the second holder bush 441b moves forward by the forward motion of the second handle bush 450b. As the drill holder portion 440 is closer to the structure (1), the first link (451a) and the first link (451b) coupled to the first handle bush (450a) that is extrapolated and fixed to the shaft (430) The second link 451b coupled to the other end of the second side 451b operates in a direction opposite to the operating direction of the handle handle 451d about the hinge h portion. In addition, the compression coil spring that is extrapolated to the shaft 430 between the first handle bush 450a and the second holder bush 441b is compressed as the second holder bush 441b moves forward.

       On the other hand, when the external force is removed from the handle knob 451d after completion of the drill processing hole for the structure 1, the drill holder 440 and the handle knob 451d are restored to the rear by the restoring force of the compression coil spring. The drill 3 mounted to the drill holder bush 442a of the holder portion 440 is moved away from the structure 1 side.

       And, when the operator operates the handle portion 450 while moving the horizontal moving bar 300 and the drill mounting portion 400 to the hole forming point of the next target of the structure (1) can easily form a continuous hole processing easily It becomes possible.

       In addition, since the drill 3 mounted on the drill holder bush 442a can be replaced as necessary to meet the working specifications, the diameter of the drill hole can be formed in a different form.

Although the drill jig for machining a hole according to the present invention has been described with reference to the illustrated drawings, the present invention is not limited by the embodiments and drawings disclosed herein, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. Of course.

As described above, the drill jig for drilling holes according to the present invention forms a hole in a structure while horizontally and vertically moving the drill mounting portion in which the drill is mounted to be positioned at a hole forming point, thereby controlling the spacing and perpendicularity between holes, and preliminary hole processing. There is an advantage in that complicated pre-work such as this is unnecessary and can improve the efficiency of the hole forming work according to the automation of the work process.

In addition, since the drill hole processing operation is made by the handle operation, the operator can perform the work in a more stable posture, there is also the advantage of less accumulation of fatigue due to the work and minimize the risk of industrial accidents.
